Science First Super Slinky Spring And Stand

This extra long slinky spring has a 3â€ diameter and stands 20cm high when compressed.) Use this spring to provide students a visual and hands on approach to demonstrate and observe wave behavior. The concern over tangling during use or storage is solved with the included stand. The accompanying teacher's guide includes the motion of waves through a medium, how waves interact with each other, how energy is transferred through a spring, and the Law of Superposition. Science educational products and manipulatives incorporate applied math and science principles into classroom or homeschool projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits, manipualtives, and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, chemistry, physics, biology, and geology.

it's just a clock. This lovely timepiece appears to have been hand written by that evil science teacher we all had to endure. Powder coated metal. Requires 1 AA battery (not included). 11-1/2" Diameter.

Thermoacoutsitc Stirling Engine

Thermoacoustic devices are very different from Stirling devices, although the individual path traveled by each working gas molecule does follow a real Stirling cycle. These devices include the thermoacoustic engine and thermoacoustic refrigerator(cold side). High-amplitude acoustic standing waves cause compression and expansion analogous to a Stirling power piston, while out-of-phase acoustic traveling waves cause displacement along a temperature gradient, analogous to a Stirling displacer piston. Thus a Thermoacoustic device typically does not have a displacer, as found in a beta or gamma Stirling.

Rite in the Rain All-Weather Notebook measuring 5 inch x 7 inch allows students to write field notes in all weather conditions as it withstands elements from the torrential downpours of the Pacific Northwest to the blistering heat and humidity of a Florida summer's day. Spiral-bound book with 64 amazing papers feature 1/4 inch rules and faint 1/4 inch grid.
